Influence of the probes on cell growth and endogenous H2O2scavenging.A, growth curve of a WT BY4742 strain transformed with an empty vector, Tsa2 WT, roGFP2-Tsa2ΔCR, HyPer7, or SypHer7. The cells were exposed to 0.25 mM of H2O2 2 h after the start of the experiment. B, growth curve of a tsa1Δ tsa2Δ strain transformed with an empty vector, Tsa2 wt, roGFP2-Tsa2ΔCR, HyPer7, or SypHer7. The cells were exposed to 0.25 mM of H2O2 2 h after the start of the experiment.
